%N Number of edges among all distinct circles that can be constructed from an n x n square grid of points using only a compass.
%C A circle is constructed for every pair of the n x n points, the first point defines the circle's center while the second the radius distance. The number of distinct circles constructed from the n x n points is A359931(n).
%C No formula for a(n) is known.
%C See A359932 and A359933 for images of the circles.
%F a(n) = A359932(n) + A359933(n) - 1 by Euler's formula.
%Y Cf. A359932 (vertices), A359933 (regions), A359935 (k-gons), A359931 (distinct circles), A359861, A359254.
